The components of a vector PQ are the differences of the corresponding coordinates of Q and P, respectively. The components of PQ can be also considered as the components of the difference OQ - OP of the position vectors of P and Q, respectively. This kind of dual interpretation comes especially handy when vector-valued functions are used to describe curves in space.
